Abstract: A method of forming nanowires, including the forming on a metal region of a layer having through openings, and the forming in the through openings of portions deposited in a chemical bath, forming all or part of the nanowires and extending from the metal region.

Abstract: A nanowire forming method, including the forming of a DNA origami having through openings, and the forming in the through openings of portions forming all or part of the nanowires.

Abstract: The piezoelectric device includes a first electrode, a second electrode, piezoelectric elongate nano-objects in contact with the first electrode, and extending between the first electrode and the second electrode, a first layer of an electrically-insulating first material, the first layer surrounding a first longitudinal portion of each of the piezoelectric elongate nano-objects, a second layer of an electrically-insulating second material, the second layer surrounding a second longitudinal portion of each of the piezoelectric elongate nano-objects. The first layer is arranged between the first electrode and the second layer. The thickness of the first layer is strictly smaller than the thickness of the second layer. The first material has a Young's modulus strictly higher than the Young's modulus of the second material.
